Thermodynamics
In these slides we will cover the following topic in detail so for the complete description download the given slides.
A device that exchanges energy with the fluid, using continuously flowing fluid and rotating blades.
e.g Aircraft Engine, Wind Turbine.
- If the device extract energy from fluid generally called as turbine.
- If the device deliver energy to fluid generally called as pump.
turbo machinery is the generic name of all these machines.
Nozzles?
A nozzle is a duct of smoothly varying cross section area in which a steadily flowing fluid can be made to accelerate by a pressure drop along the duct. Nozzles are used in steam turbines, in rockets,in injector and ejector etc.
Diffuser ?
When a fluid is decelerated in a duct causing a rise in pressure along the steam. e.g centrifugal pump etc.

As you know nozzle is a duct of smoothly varying cross section area in which a steady flowing fluid can be made to accelerate by a pressure drop along the duct. e.g nozzles are used in steam and gas turbines, in jet engines, in rocket motors etc.
In this lecture we will discuss the nozzle briefly.- Diffuser
When a fluid is decelerated in a duct, causing a rise in pressure along the stream. Its major applications are centrifugal pumps and ramjet.
- We will also discuss diffuser briefly.
- We have a long discussion on Nozzle Shape.
- Convergent Divergent Nozzle.
- Critical Pressure Drop
- Critical Temperature Ratio
- Critical Velocity
- Maximum Mass Flow
- Nozzle Off the design pressure ratio
- Convergent Nozzle
- Convergent Divergent Nozzle
- Nozzle Efficency
- Length of Nozzle
- The Steam Nozzle
All of the above topics are discussed in detail in the above given slides.
